An Indian teenager has built what is thought could be the world's lightest satellite, which will be launched at a NASA facility in the US in June.
Rifath Shaarook's 64-gram (0.14 lb) device was selected as the winner in a youth design competition.
The 18-year-old says its main purpose was to demonstrate the performance of 3-D printed carbon fibre. The lightweight satellite will operate for around 12 minutes in a micro-gravity environment of space. It will have a new kind of on-board computer and eight indigenous built-in sensors to measure acceleration, rotation and the magnetosphere of the earth. The satellite has been named KalamSat after former Indian president Abdul Kalam, a pioneer for the country's aeronautical science ambitions.
